The influence of Structural Dynamics in Two-Dimensional Hybrid Organic-Inorganic Perovskites on their Photoluminescence Efficiency -- Neutron scattering analysis
Haritha Sindhu Rajeev, Xiao Hu, Wei-Liang Chen +12
Two-dimensional hybrid organic-inorganic perovskites (HOIPs) have emerged as promising materials for light-emitting diode applications. In this study, by using time-of-flight neutr…
Freezing of a disorder induced quantum spin liquid
Xiao Hu, Daniel M. Pajerowski, Depei Zhang +8
is a square-lattice magnet with super-exchange between S=1/2 spins mediated by randomly distributed Te and W ions. Here, using sub-K…
Temporally-decoherent and spatially-coherent vibrations in metal halide perovskite
Depei Zhang, Xiao Hu, Tianran Chen +8
The long carrier lifetime and defect tolerance in metal halide perovskites (MHPs) are major contributors to the superb performance of MHP optoelectronic devices. Large polarons wer…
Spin dynamics of the antiferromagnetic Heisenberg model on a kagome bilayer
Preetha Saha, Depei Zhang, Seung-Hun Lee +1
We study the spin dynamics of classical Heisenberg antiferromagnet with nearest neighbor interactions on a quasi-two-dimensional kagome bilayer. This geometrically frustrated latti…
Memory effect and phase transition in a hierarchical trap model for spin glass
Depei Zhang, Tianran Chen, Marija Vucelja +2
We introduce an efficient dynamical tree method that enables us, for the first time, to explicitly demonstrate thermo-remanent magnetization memory effect in a hierarchical energy…
Plaquette order in classical spin liquid stabilized by strong off-diagonal exchange
Preetha Saha, Zhijie Fan, Depei Zhang +1
We report a new classical spin liquid in which the collective flux degrees of freedom break the translation symmetry of the honeycomb lattice. This exotic phase exists in frustrate…
